Title: Gas cock for automatic ignition
Inventor: YAMADA ICHIZOU
IPC: F16K31/11
Filed: 1980-01-23
Abstract: PURPOSE: To ensure the operation and improve the safety of the device by a method wherein an operation mechanism is constituted with a cylindrical cam, a pivoting cylinder and a pushing shaft.  
     CONSTITUTION: When an operating shaft 60 is pivoted, the pushing shaft 53, the pivoting cylinder 52 and a closing piece 20 are pivoted. In this case, the retaining protuberance 52b of the pivoting cylinder 52 is slided on the inclined cam surface 51b of the cylindrical cam 51 an the pivoting cylinder 52 is lowered under being pivoted while the pushing shaft 53 is also lowered together with the pivoting cylinder 52 and pushes an auxiliary valve 30 downwardly. Concurrently, the shaft 53 pushes the piston valve 42 of a solenoid safety valve 40 downwardly. As a result, the internal hole 21 of the closing piece 20 and a gas inlet port 11 are communicated and a main burner (not shown) is ignited. When the main burner is ignited, an electromotive force is generated in a thermocouple 44 and the piston valve 42 is attracted to the side of a valve main body 41 to keep the opened condition of the solenoid safety valve 40 thereby enabling the sure operation of the device.

Title: Electric power supply device
Inventor: RIYUUSAKU SEISHI
IPC: G05F1/455
Filed: 1981-01-21
Abstract: PURPOSE:To stabilize a load at an early stage, by temporarily increasing electric power supplied to the load. CONSTITUTION:An output level of a level setting device 5 is set to a load of normal power consumption. When an on-off command device 6 is turned on, the level setting device 5 outputs a prescribed level, but a rise compensating device 7 operates and supplies an output whose level is higher than the prescribed level to a control device 4, therefore, supply of electric power to a load 2 is started by supplying electric power B which is larger than an electric power A corresponding to a normal level. Accordingly, since the load 2 is operated by a large electric power B at first, it is stabilized earlier than the case when the electric power A is supplied from the beginning. After that, the electric power A is supplied to the load 2.

IPC: G01T1/20
Filed: 1979-01-23
Abstract: PURPOSE: To attempt to shorten the measuring time, simplify the construction of the device and improve the reliability thereof by arranging a plurality of radiation detectors around the circumference of a body to be detected, and arranging radioactive shielding thin plates around the circumference of the body as described above.  
     CONSTITUTION: Detectors 31, 32 are arranged radially on a circumference 4 where the gamma-ray incident surface is brought into contact with the circumference 4 concentric to a fault image reconstruction range 2. The thin plates 51, 52,... of a collimator 5 are supported on the circumference 4 so that they can swing around points 61, 62... on the border of adjacent detectors 31 and 32. Since gamma-rays irradiated from the body 1 to be detected pass through gaps between auxiliary thin plates 71, 72... and reach one detector, collimation in the direction of the circumference 4 is improved. When the thin plates 51 and 52 are swung, the auxiliary thin plates 71, 72... swing. For this reason, gamma-rays in various directions can be detected by the same detector, and the entire data can be obtained in a short period of time. Further, since the collimator 5 is constituted by thin plates, the construction of the device can be made compact, and since the detectors 31, 32... are fixed, the reliability of the device can be improved.

Title: Method and device for digital signal processing
Inventor: KIMURA KAZUHIRO
IPC: H04L1/00
Filed: 1995-01-20
Abstract: PURPOSE: To reduce the current consumption accompanied with the operation by referring to the decoding discrimination bit included in each block to control the access to a frame buffer at the time of the error correction processing in the longitudinal direction or the second error correction processing. CONSTITUTION: The digital signal which has error correction codes in the lateral direction and the longitudinal direction and includes a control bit part in the lateral direction is inputted to a frame buffer RAM13 through a synchronous reproducing part 11 and a RAM controller 12. The controller 12 reads out a one-block portion of the signal from the RAM 13 and outputs it to an error corrector 14, and error correction is performed in accordance with the parity code. If error is detected by a CRC circuit 15, rewrite to the same address position as the read position of the RAM13 is performed. Next, a one-frame portion of the signal is read out from the RAM13 in the longitudinal direction, and error correction in the longitudinal direction is performed by the error corrector 14.  In this case, the decoding discrimination bit in the same block is referred to by a decoding discrimination detector 20, and rewrite to the RAM 13 is not performed with respect to the block where this bit is '1'. Thus, the frequency in access is reduced.
